使用Python API时Google App Engine任务队列错误

Question

我在做一个Flask和GAE的项目，想学习更多关于Python网页开发的知识，结果遇到了一个错误，我找不到任何相关的信息。

----------------------------------------
Exception happened during processing of request from ('0.1.0.2', 80)
Traceback (most recent call last):
 File "/usr/local/Cellar/python/2.7.1/lib/python2.7/SocketServer.py", line 284, in    _handle_request_noblock
self.process_request(request, client_address)
File "/usr/local/Cellar/python/2.7.1/lib/python2.7/SocketServer.py", line 311, in process_request
self.shutdown_request(request)
File "/usr/local/Cellar/python/2.7.1/lib/python2.7/SocketServer.py", line 459, in    shutdown_request
request.shutdown(socket.SHUT_WR)
AttributeError: 'FakeConnection' object has no attribute 'shutdown'
----------------------------------------

我有一个视图（也就是处理请求的部分），它接收来自我应用中另一个视图的POST请求。根据我的观察，它的处理过程都正常，直到最后却出现了这个错误。我猜测是因为在GAE的开发服务器日志中看到了这个输出：

INFO     2011-01-23 21:41:16,865 dev_appserver.py:3317] "GET /main/new HTTP/1.1" 200 -
INFO     2011-01-23 21:41:23,753 dev_appserver.py:3317] "POST /main/new HTTP/1.1" 302 -
INFO     2011-01-23 21:41:24,528 dev_appserver.py:3317] "POST /tasks/check_for_spam HTTP/1.1" 200 -

check_for_spam的部分是一个函数，它会把一些数据传给Defensio API，来判断这些数据是否是垃圾信息。以下是相关的代码：

from google.appengine.api import taskqueue
from google.appengine.ext import db
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app

from application.models import LieModel
from defensio import *

class SpamChecker(webapp.RequestHandler):
    def post(self):
        id = self.request.get('id')
        client = Defensio('577709b41d42f2c34f80cd57d50333d6') 
        q = LieModel.all()
        q.filter("id = ", id)
        results = q.fetch(1)

        for result in results:
            title_doc = {'content': result.title, 'type': 'comment', 'platform':'python'}
            body_doc = {'content': result.body, 'type': 'comment', 'platform':'python'}
            title_status,title_response = client.post_document(title_doc)
            body_status,body_response = client.post_document(body_doc)
            lie_is_spam = False

            if title_status == 200 and title_response['defensio-result']['spaminess'] > 0.5:
                lie_is_spam = True

            if body_status == 200 and body_response['defensio-result']['spaminess'] > 0.5:
                lie_is_spam = True

            if lie_is_spam:
                lie_k = db.Key.from_path('Lie', id)
                lie = db.get(lie_k)
                lie.delete()


def main():
    run_wsgi_app(webapp.WSGIApplication([
        ('/tasks/check_for_spam', SpamChecker)
        ]))

if __name__ == '__main__':
    main()

如果能帮我解决这个问题，我会非常感激。
